A planted or green roof defines that part of the surface of the roof of building which is covered with plants, and consistsof the suitable infrastructure (anti-root membrane, drainage system, fitlers, growing soil substrate, the plants, and the irrigation system)
Extensive: Hardly low vegetation plants with the use of a thin growth medium of up to 15cm. This is anon-accessible roof, with low consturction cost, requiring only limited maintenance. The planting medium is capable of holding a certain quantity of water. The load ranges 70 to 140 kg/m2 saturated, and the root system of the plants is shallow.
Intensive: Intensive planting requires a great thickness of the soil layer, and usual garden plants (grass, low bushes and small trees). Roofs with intensive planting are regarded as accessible, and pedestrian walkways are used. The planting zone must be large, as must be the drainage zone.
Semi-extensive: Consisting of an infrastructure system and a light underlay for plant developement of a depth of 10 to 25 cm, with a saturated load of 120 – 250 kg/m2. This is the intermediate, between the intensive and the extensive type; it is applied to sloping or level roofs and requires maintenance (irrigation, fertilisation, etc.). The diversity of species used includes natural grass, lawns, herbaceous plants, and small / medium-size bushes.
What are the benefits?
The benefits from the consturciton of green roofs are invironmental, economic, and social:
Reduction of urban heat island effect by means of an imporvement in the microclimate by lowering the surface temperature by up to 40ºC compared with classic roofs, and therefore a reduction in the energy footprint by means of a decrease in the amount of the emision of CO2 into the air.
Decrese of the burden on sewage systems by 70 – 95% in summer.
Improvement of the quality of the air by reason of the absorption of airborne particles (e.g. smog, heavy metals, volatile organic compounds).
Creation of a natural habitat because of the creation of a microclim,ate and of the condition for the developemnt and accommodation of a biodiversity which has beend disturbed by excessive urban developement.
Increased lifespan of the roof because of its protection from ultraviolet radiation.
Reduced costs for maintenance and renovation.
Improved energy yield by energy cost savings by 25% for heating and 75% for cooling fo energy consumption.
Positive psychological impact because of a feeling of relaxation on the part of occupants.
Development of mini-crops within the urban fabric, thus reducing the consumer environmental footprint, and giving a sense of self-sufficiency in food resources to users.
MONOTECH applies an innovative, lightweight, easy to install system, with high water retention capacity, designed specifically for green roofs on homes, and commercial and industrial buildings in urban areas.
This consists of TPO membrane, a drainage system with or without extra water storage, a growing medium – a unique patented rock mineral wool substrate – and a vegetation layer.
